Abstract
Reactions of naphthaleneeuropium and naphthaleneytterbium, C10H8Ln(DME) (Ln = Eu or Yb), with phenylacetylene are accompanied by the formation of the C-C bond and yield the complexes of composition Ph2C4H2Ln(DME)2. Hydrolysis of the Ph2C4H2Ln(DME)2 complexes affords a mixture of isomers of 1,4-diphenyl-1,3-butadiene. Reactions of C10H8[LnI(DME)2]2 with PhC≡CH yield mixed iodine-ethynyl complexes [ILn(μ-C≡CPh)(DME)2]2. According to the data of X-ray diffraction analysis, the ytterbium complex consists of two YbI(DME)2 units bonded through two bridging C≡CPh groups. The crystals of this complex belong to the space groupP21/c. The central cyclic Yb-C-Yb-C fragment is planar; the C(I)-Yb(I)-C(I′) angle is 86.4(3)°. The Yb-C bond lengths are 2.584(8) and 2.603(9) Å.
